Step 1: Basicity of Ethylamine and Ammonia.
Ethylamine (\(C_2H_5NH_2\)) is more basic than ammonia (\(NH_3\)) because the ethyl group (\(C_2H_5\)) is an electron-donating group. It pushes electron density towards the nitrogen atom, making it more nucleophilic and able to donate a lone pair of electrons more readily than ammonia.
Step 2: Conclusion.
Thus, ethylamine is more basic than ammonia due to the electron-donating effect of the ethyl group.
